Amid the growing speculation about Apple's next-generation iPhone, a new report suggests that the tech giant is working on a big screen iPhone and iPad.

According a Wall Street Journal report, which has a credible track record of Cupertino's developments, a bigger iPad and iPhone may be on the cards. The report also cited Apple's Asian suppliers confirming the news that the company is currently testing bigger screens for iPad and iPhone. The report also said that Apple has recently asked its suppliers to deliver prototype screens larger than four inches for its next-generation iPhone and also ordered a large screen design for iPad which measures slightly smaller than 13 inches.

It still remains unclear whether Apple will introduce this to the market, taking note that the company has the record of testing different designs at different times.

WSJ also mentioned that the suppliers are working to ramp up production of the next generation iPad later this month, which is speculated to come with the same existing 9.7-inch model screen seen in its predecessor. However, the upcoming tablet is said to feature a lighter and thinner display from the current model and may have touch sensors with a thin film replacing the traditional glass. The suppliers are said to have begun mass production of iPhone components and the company has asked its Hon Hai Precision Industry Co/Foxconn to be prepared for shipments of the iPhone in late August.

The latest report supports the previous rumour that Apple is prepping a big iPad. Earlier this year, South Korean publication ET news had reported that Apple is prepping a 12.9-inch tablet touted as iPad Maxi.

Rumours about Apple's next generation iPad and iPhone have been doing the rounds for quite some time. Another report suggested that Apple's iPhone 5S would come with a thin bezel, while the upcoming iPad with Retina Display will adopt the iPad mini design.
